To all whom it may concern:

Be it known that I, SIGVORT O. HAGEN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful 'Valve, of which the following is a specification.

It is the object of this invention to provide novel means whereby the supply of steam to a radiator may be controlled by air pressure, responsive to a thermostat.

The invention aims, specifically, to improve the valve mechanism which controls the flow of steam to the radiator or like device.

\ It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to'which the invention appertains.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention, the view being diagrammatic to some extent, and illustrating the application of the structure hereinafter claimed; Figure 2 is a vertical section taken through the valve casing and'attendant parts, portions appearing in section; Figure 3 is an'elevation looklng' at the bottom of the valve; and Figure 4 is av fragmental sectional view, similar to Figure 2 but showing a slight modification.

Referring to Figures 1, 2 and 3, the numeral 1 denotes, generally, a valve casing, the valve casingincludingatubular body 2 having an outlet 3 and an inlet 4, the inlet and the outlet being rotated as occasion may require. A connection 5 unites the outlet 3 with a radiator 6. A steam line- 7 is connected to the inlet 4. A partition 8 extends across the body 2 of the valve casing and is located between the inlet- 3 and the outlet 4, the partition 8having an opening into which is threaded a seat 9 having a flange 10 cooperating with the upper surijace of the partition. A to 11 rests on the upper end'of the body 2 an carries a combined guide tube and conduit 12 which projects both above and below the top, the tube 12 being closed at its lower end, as shown at 14. Stated glitterently, the tube 12 may be described as being provided intermediate its ends with an outstanding disk, represented by the top 11.

The tube 12 has side ports 15 located relativel near to the closed end 14 of the tube. A ii 16 is threaded at'17 on the body 2 and 1920. Serial an. $78,289.

end oi the tube 12 pro'ects through the lid 16. A: nut 19 is threa ed on the projecting end of 'the tube 12 and engages the lid 6 to 7 hold the parts rigidly assembled. An elbow 20 is threaded into. the u per end of the tube 12 and forms part of an air ressure line 21, in which a thermostatic va ve 22 is interposed.

An expansible member, such as a metal bellows 23, is located within the body 2, the upper end of the bellows being secured to the dislg 11, the bottom of the bellows being indicated by the numeral 24. The numeral 25 marks a valve adapted to cooperate with the seat 9, the valve 25 having depending rectangularly arranged wings 26 which, be-

. ing slidably received in the seat 9, serve to guide and direct the movement of the valve 25, without, interfering with the passage of steam through the seat 9 when the valve 25 is raised, as shown in Figure 2 of the drawings. The valve 25 has a neck 27 carrying a broadened head 28 abutting against the bottom 24 of the bellows 23. A stem 29 projects from the head 28 and passes upwardly through the bottom 24 of the bellows 23, the stem being slidably'received in the lower end 14 of the -tube 12. Anut 30 is threaded on the stem 29 and cooperates with steam may pass from the line 7 through the seat 9 and into the radiator 6, by way of the connection 5. The thermostatic valve 22 may be set to permit the assage of air under pressure through the line 21, at any given temperature. When that temperature has beenattained, the air under pressure traverses the pipe or line 21 and enters the tube 12 by way of the elbow 20. The pres sure passes into the bellows 23 by "way oi the ports 15, the bellows is expanded and the valves 25 is thrust downwardly against the seat 9, the passage of meam through the the upper surface of the bottom 24 of the seat 9 to the radiator 6 thus being stopped. When the temperature of the room has cooled suificiently, the thermostatic valve 22 will cut ed the supply of air to the bellows 23, whereupon the spring32 will reassert itself and raise the valve 25 to open position, thereby permitting the steam to pass again to the radiator.

It may occur that the bellows 23 or some other part of the device may get out of order. Again, although the device may be in working'order, it may be preferred to operate the valve 25 by hand. Under such circumstances, recourse is had to a mechanical means under the control of an operator, and adapted to cooperate with the stem of the valve, to seat the valve, said means being shown in Figure 4 of the drawings. In Figure 4, parts hereinbefore described, have been designated by numerals previously used, with the sufiix In Figure 4, the nut 19 has been remoi'ed, its place being taken by a cap 33, the air line 21 having been disconnected. Into the cap 33, a screw 34 is threaded, the same having an external hand wheel 35. The inner end of the screw 35, obviously, is adapted to cooperate with the'nut 31 on the upper end of the valve stem 29 to effect a depression of the stem and the valve, all of which will be obvious when Figure 4 is compared with Figure 2. v

Having thus described what is claimed is a x 1. In a device of the class described, a casing having a seat; an expansion member carried by the casing a valve forced by the expansion of said member tocooperate with the seat, the valve having a stem; a tubular guide carried by the casing, the stem being slidable therein, the guide communicating with the expansion member; spring means in the guide and cooperating with the stem to retract the valve from the seat and to compress the expansion member; and a fluid pressure line communicat-, ing with the guide. I

2. In a device of the class described, a

the; tube having a port communicating with the expansion member avalve carried by the expansion member and cooperating with the seat, the valve including a stem slidable' in the tube; an abutment on the stem; and a compression spring interposed between the abutment and the tube and constitut-.

ing means for moving the'valve to, open position with respect to the seat. a

3. In -a device of the class described, a casing having an inlet and an outlet; a seat between the inlet and the outlet; a disk mounted .on the casing and provided with a tube extending into the casing; an

expansion member carried by the disk, the tube communicating with the expansion member; a 'valve' mounted on the expansion memberandcooperating with-the seat, the valve comprising a stem slidable in the tube; an abutment on the stem; and a spring interposed between the abutment and the'tube and constituting means for moving the valve to open position with re-- spect to the seat.

,. structed as set forth in claim 1, and further characterizedby mechanical means under the control of an operator and adapted to cooperate with the stem to seat the valve; and mechanism for assembling said mechanical means and the fiuid'pressure line, interchangeably, with the guide, at the will of an'operator. v

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in thepresence of two witnesses.
